ATENT OFFICE ASSIGNOR To run nnvrs AND son mu- FAOTUBIHO' COMPANY, OFDENVER, COLORADO, A CORPORATION OF. COLORADO OIL-DiSPENSING nEvIcnApplication filed April 20,

This invention relates to improvements in oil dispensi devices of thetype, shown and described in nited States Letters Patent No. .1,601,200,granted to me on Septemb'er'28, .1926.

" It is customary for gasoline service stationsto dispense lubricatingoil in measured quantifies and for the convenience of serving clientswith lubricating oil, it is desirable to have an apparatus from whichthe o'ilcan be quickly drawn into measures. In the patent aboveidentified, a device of this type has beenshown and described in whichthe;

oil is contained in a tank located under ground and subjected tosufficient-air pressure to cause it to flow upwardly through pipes tothe dispensing valves. r

It has been found that it is; often desirable to provide a dispensingdevice which will be self-contained and "which can therefore be put inplace without the necessity of excavating for the purp os'e of placingtanks under ground.

It is the object of this invention to produce an oil dispensing devicewhich shall be so constructedtha-t it can be quickly put intoyplace onany level supporting surface and which shall have a base that contains aplurality of airtight tanks which are adapted to contain'diiferentgrades of lubricating oil. Extending upwardly from the base is a dis 1play device having a dispensing head from opposite sides of whichdispensing valves project. These dispensing'valves are controlled bymeans of a spring and the oil containing tanksv are subjected. tosuflicient air pressure to cause the oil to flow upwardly to thedispensing valves.-

Having thus briefly described the invention, the same will now bedescribed in detail, and reference for this purpose will be had to theaccompanying drawings in which- 1928. Serial at. 271,503.

Fig. 5 is a section taken on line 5-5, Fig. 2;

Fig. 6 is a vertical'section similar to that 4 shown in Fig. 3, butshowing a slightly modified formof tank; and

In the drawin numeral 1 designates a cast iron ring which is adapted torest upon the supporting surface2 and which hasan upwardly extendingflange 3, which cooperates with the enclosing shell 4. Ring 1 'is alsoprovided with a plurality of supporting bars '5 that have their endswelded to the ring and which serve as supports for the oil tanks A andB.- These oil tanks have a transverse section like that shown in Fig. 4from which it will be seen that .one side isformed by /a metal plate 7,that is curved in the are of a circle and has its edges secured to theedges of the flat plates 8 and 11. These tanks are provided with tops 9and bottoms 10 and are of unequal .size. The tanks when in line placewithin thecasing are so'located that the. I

ourved sides 7 are concentric with the'e'nare put into place there willbe a space C between the vertical sides'8. -This space providesapassageway through which the discharge pipes 12 may pass and they alsoprovide a space for the reception of the electric heaters 13. Theseheaters are secured'to the upper ends of brackets 14 by means of screws15 and these brackets have their lower ends secured to the ring 1 bymeans of screws 16 in the manner shown in Fig. 1.

Further reference will be'made to the electric heaters as these areconsidered to be an important part of this invention.

Resting on the upper edge of the cylindrical enclosing shell 4 isanother ring which hasbeen designated by numeral 17. This rin has adownwardly extending flange 18 WhlCh fits within the upper end of thecylindrical shell in the manner shown in the drawings. Extendingdiametrically across ring 17 is an integral member 19 having anelongated central opening 20 whose upper edge is provided with anupwardly extending by means of removable covers'26 which are heldinplace by bolts 26'. Located above the opening 20 is a dispensing head27, which is provided with a plurality of chambers with whichwdispensingvalves 28 are in cognmunication. This dispensing head is su portedonthebolts 23 whose lower ends pass t rough openings in the webs 22. Asthis dispensing head has been described-in mypatent above identified; itwill not be-described in" detail here. Supported on-the dispensing head27 are a plurality of glass jars 29 which contain samples of the oilwith which the corresponding valves are in communication. The displayJars are surmounted by an ornamental metal cap 30, which rests upon abase 31 that is secured to the dispensing head by means of bolts 32. Atranslucent globe 33 1s secured to thetop of the hood 30 and is'adapted'to contain a lightwhich is periodically flashed. A metal shell34 extends from the member 19 to the under surface of the dlspensinghead 27 and serves to enclose the space between the transverse memberand the dispensing head so as to providea; chamber through which thepipes 12can pass. Each.

one of pipes 12 is connected to the lower end of one of the tanks A andB and has its other end connected to one of the chambers in thetransverse dispensing head 27 so that 'each of the dispensng valves 28is in communication with the bottom of one of the oil tanks via achamber in the dispensing head. i

' In order to make the oil flow vfrom the tanks to the valves'28, it isnecessary to introduce .air under pressure into .the tank compartmentsin the space above the top of the oil and the top plate 9 of the tanksand for this purpose I have provided a system of pipes so that the airconnections can be readily made. Located within the space C isanair-reducing. valve 35, whose delivery port is connected to a. cross 36.A safety valvefl37 is connected to the top opening of the cross and apressure gauge 38 isconnected to the lower opening. The side openingfarthest away from' the reducing valve is connected with a T 39. Fromthe; opening in the bottom of the T 39 a brass tube 40 extendsdownwardly and is curved in the manner shown in F ig- 2. This t be. iscon= nected at 41 and 42 with the interiors of tanks A and B on one sideof the space C between the two sets of tanks. A similar tube 4O extendsfrom the top of the T 39 and is connected with the interiors of thetanks A and B on the opposite side of space C at points 41f and 42. Fromthe intake opening of the reducing valve a pipe 43 extends to a T 44 towhich the pipes 45 and 46 are connected. A valve 47 is located in pipe43 between "the T Maud the reducing valve 35. Pipe 45 extendsupwardly sothat connection can be made with the air supply of the service stationby means of an overhead pipe (not shown). If the air supply is solocated that an underground pipe is preferable, the cap 48 can beremoved from the lower end of pipe 4e and connection made with a pipefrom the air tank. In this latter case plpe 45 can be removed andreplaced by a'plu'g.'

Electric current for the heaters can be introduced through "the conduit49 and electric wires willipass through the flexible conduits 50 to thejunction boxes 51 of the heaters. Secured to the upper ring 17 are twosegmental shaped combined supporting tables and drip pans. These areeach c omposed of a shallow pan, 52, whose upper side is closed by meansof a. perforated plate 53. Each' plateg53'is secured to a pan 52 bymeans \of screws 54 so that the two parts will remain in assembledrelation. These combined supporting tables and drip pens are of suchsize I that they fit. the space between the central member 19 and theinner surface of ring 17 in the manner clearly shown in Fig. 2. In

dispensing oil it often times happens that a readily removed andreplaced. It is quite often necessary to remove the drip pans so as togive access to the fill openings through which the j oil is introducedinto thetanks A and B. These fill openings are closed by screw plugs 57.I

I desire to call particular attention to the great convenience in theinstallation of "machines constructed in the manner described as theyare entirely self-contained and can be quickly put in place on. any fiatsupporting surface. the air and with the electric current sup: ply canbe readily and quickly accomplished The connections with as there are nounderground pipes to be laid.

The location of the a r-red ing valve 35 within the device is a greatconvenience as the parts are located in such a way that they cannot beinterfered with by unauthorized persons and they can also be put intoplace in the factory, thereby assuring good work manshi p and tightconnections. The electric heaters 13 are ofgreat importance in colderclimates. as without heaters of some sort,

. the lubricating oil will congeal to such an extent that it will notreadily flow, and when this occurs the apparatus becomes practicallyinoperative. The space C between the two sets of tanks forms acompartment which contains the dispensing pipes 12 and therefore sincethe heaters are located in this compartment, these pipes will be keptwarm, even during the coldest weather and besides this, the Ilse/of thecompartment, as shown, makes it possible to more efficiently use theheat generated as it is stored in this compartment from which it isabsorbed by the lubricating oil within the tanks.

In Figures 6 and 7 I have shown a modified construction in which thetanks corresponding to tanks A and B are arranged in superposedrelation, that isto say there are two segmental shaped tanks B, one oneach side of the compartment C and respectively disposed above two tanksA, which are also respeclively located .on opposite sides of thecompartment C. The bottom of each tank B rests upon the top of a tank Aas shown at 55. The delivery pipes 12 connect with these tanks neartheir bottoms and the air supply is connected with each tank near thetop. Tanks B have fill openings 56 that are closed by screw plugs 57 Itis, of course, necessary to introduce oil into the lower tanks A andthis is accomplished by providing a tube 58 whose lower end extendsthrough an opening in the contacting walls 55 of the tanks B and A towhich it is secured as shown at 59. The upper end of each tube 58extendsthrough an opening in the top of the tank B and is securedthereto as shown at 60. The upper ends of tubes 58 are closed by meansof screw plugs 57.

The tanks A and B and A and B are formed independently and theindividual tanks of each pair may be spot welded at different places orotherwise connected so that they are practically unitary as far ashandling is concerned. It has been found that there is animportantadvantage in constructing the tanks separately as aboveexplained, rather than forming large tanks and'dividing them bypartitions into separate compartments, since if there should be anyleaksin the separate tanks, oil will become visible on the outside sothat the leaks will be readily discovered, whereas if a partition isplaced in a tank so as to divide it into two compartments, a leak inthispartition would not be quickly discovered and therefore the twodifferent grades of oil would intermix. The

term pressure reducing valve assembly as used in the claims must beunderstood to mean the reducing valve proper, the air gauge, the safetyvalve and their necessary pipe connections as best illustrated in Fig. 1of the drawing.
